Open Source C++ SQL Clients

A free, open-source, multi-platform SQLite database manager written in C++, with use of Qt framework. It's free of charge for everybody, for any purpose (including commercial). It's safe, as anyone can review the source code. The SQL Editor window assists users with SQL syntax hints & highlighting, provides pretty-print code formatter, and marks syntax errors. You can Ctrl+click on the table mentioned in the SQL query to open that table (or index, or trigger, or view). Currently supported encrypted, password-protected SQLite variations are SQLCipher, WxSQLite3, and System.Data.SQLite. You can execute SQL statements that refer to multiple databases within a single query, thanks to a transparent database attaching mechanism built into the SQL Editor of SQLiteStudio. You can implement your own SQL functions (scalar & aggregate) using JavaScript, Python, or Tcl. There is a repository of ready-to-use scripts on the wiki page.
